London Borough of Bromley standards at a glance

2 numeric standards taken from London Borough of Bromley's own adopted documents, each shown with the paragraph it comes from. Figures differ between councils — these are this one's.

Side extension form

at least 1m

Bromley have a firm rule: anything two storeys or more must keep a metre clear of the side boundary, all the way up and all the way along. If the houses around you are more generously spaced than that, they will expect you to match the street rather than the minimum. Bromley Local Plan Policy 8

at least 1m

A two-storey extension in Bromley needs a metre clear of the side boundary, held for the whole height and the whole length. If the houses around you sit further apart than that, expect to be asked for more. Bromley Local Plan Policy 8 (Side Space), criterion a (provisional citation)

Standards are what the council normally expects, not a guarantee. A scheme outside them can still be approved on its merits, and one inside them can still be refused for another reason.

Authored Policy Library

4 local policy checks, each citation-locked to the adopted document. National policy (NPPF, national space and daylight standards) applies alongside these.
